In 1x02 episode, sheriff looks pretty interested in Patrick's appearance, immediately starts asking questions about him- somehow, being suprised. He is like: ''You?! What the hell are you doing here?''. If Tom is really Red John, that's the kind of reaction you would expect from him- he remembers Patrick only as someone who mocked him through public television, false psych from whom he took his family away, as a punishment. And now, suddenly, he is here again, helping CBI! The game of rock-paper-scissors finally triggered rivalry between the two of them.

Hi all,
I started watch The Mentalist one month ago (today is 11.03.2013) and I am at season 5 episode 8.

Red John had appeared on 2nd season episode 8 (His Red Right Hand) to us. Since that episode I was trying to find RJ's reappeared scenes. But I failed yet.

On S2E8, it is very clear that Rebecca loves and admires Red John. Before she died, she smiled the person who put poison on her hand. She smiled, when she saw that man, like someone may had when saw her/his love or who saw the person her/his admires. Not anyone else she/he knows.

So, it is not a very clear clue but this is the trick when the "mentalism" take role. A "mentalist" can understands meaning of that smile. Of course not all of the viewers are a mentalist so Rebecca help us to reveal this with very distinct and bright smile.

The man who put poison on her hand, wore a blue high collar tshirt under his uniform. It is clearly appeared on that scene for just in a second. Please play that scene frame by frame, It is impossible to miss.

Now lets return to the press release of Minelli about Sam Bosco and his team. The camera reaches press release from Minelli's back. On that scene there is a brown van stands on right behind Minelli. 
And there is two cops in uniform with hats each side of Minelli and a swat guy stands behind him.

Right after that scene, when we see Minelli in front of him, there is a policeman appeared on his right shoulder, who wears blue high collar tshirt under his uniform.

Take a look again. Where did brown van go? Apparently there are police motorcycles with RJ and his coleague, but when camera angle changed to behind of Minelli van re-appears.

It is a shooting mistake or not. Clearly the scene that we can see Minelli's face designed to show us that blue high collar policeman.

Here ladies and gentlemen we already met with RJ.

He is a policeman who works at CBI. Of course he is humble, takes his places lower level of organisation, not on the surface. Well played RJ.

To RJ:
I dont know who you are yet but I have your portrayal. If PJ had this info, you already doomed man. Here a smiley for you :)

Either Ray is a great actor or when he confronts Lisbon about her thinking he is RJ, he actually looks hurt by it or its my imagination. Also cannot wait for the next ep http://www.cbs.com/shows/the_mentalist/video/6QKcl_lbrFvdgG5qS92rlN28_qUL7Art/the-mentalist-behind-t....

There's kind of a problem. Look at this...

Bob Kirkland: Dead
Brett Partridge: Dead
Reede Smith: Too fat/tall
Bertram: Too tall/bald
Bret Stiles: Too old/ would have been recognised on the farm
Ray Haffner: Too tall
Sheriff McAllister: Has a moustache Rosalynd never mentioned and the gruffest voice.

People not on the list: Why would we waste a whole season to make a list that didn't contain Red John? Walter Mashburn the best off-lister is a giant. He's 6"3. 

Michael Kirkland:

-Technically his face is on the list. I never got why Patrick carried pictures of people on the list.

-Experienced hypnotist

Michael Kirkland was in the carnival (Bob says to Lisbon "We moved around first for Mom's work, then for Dad's work. I like to think we grew up in America).  Bob thought Patrick was Redjohn, the person that Michael at some point met. Patrick was in the carnival. So it makes sense Bob and Michael were also in the carnival.

- Michael Kirkland kills Jason Lennon

"It's ooook, I'm heere for you. I WON'T leeaaave you."- He's doing a sarcastic impression of his brother, Bob, who actually left Michael with his abusive father.

"Your mind is clear."- Hypnotism from the carnival. 

- Michael Kirkland has a strange voice, as quoted by the little girl in season 4

- The Red Sweater Man in Strawberries and Cream: Part 2 may have been a stand in for Michael Kirkland until he was cast permanently. Bruno Heller says we see a glimpse of the real Red John that episode.

- Could hypnotise Kristina Frye to think she was dead

- Has a property (Bob's torture chamber) which could have given him the smell of pine and earth as said by Rosalynd Harker

- Michael Kirkland met Bret Stiles possibly, who helped him with his addiction

- Relates to Lisbon as their fathers were both alcoholic

- Knows Sean Barlow, since he was around the carnival circuit, who also says “It's
odd, isn't it? How the daughters of alcoholics,
so often, are the best kind of women.”

I run out of useful information here. Not much in season 6 suggests this
guy is Red John.
